F. HYDRAULIC LASH ADJUSTER
1. Hydraulic Lash Adjuster supports the pivot end
of the rocker arm while automatically
controlling the rocker arm position to keep it in
contact with the camshafts and valve.
2. The range of the hydraulic lash adjuster
accommodates engine build tolerances; hence
no adjustment is required during engine
assembly. It also compensates for variation
that occurs during the life of the engine.
3. Check lash adjuster for functionality, replace if
necessary.
